Propagation Model (0.1to 20GHz) Extensions for 1977Computer Programs,

摘要

This report describes methods used in the 1977 extensions of the propagation model incorporated into computer programs for propagation and interference analysis (0.1 to 20 GHz). These extensions to the 1973 Model allow the programs to be used for a wider variety of problems such as those involving air/air or air/satellite propagation. Method descriptions are confined to mathematical formulations for modifications to the 1973 Model, and do not include program listings or flow charts. A detailed description of the 1973 Model, including program listings, is provided in DOT Report FAA-RD-73-103. Capabilities of the 1977 computer programs are mentioned, but not discussed in detail. These capabilities are covered in DOT Report FAA-RD-77-60 which is an APPLICATIONS GUIDE for the programs. (Author)
